The curve is learned manually in the following steps:

• Release switch after normalization for max. 5 seconds.
• Then hold down the switch in the raising position direction until such time that the slide/tilt sunroof has returned to the closed position after a complete opening movement.
• This concludes learning of the curve. The switch can now be released.

In these cars, the curve is learned automatically during operation by way of the module.

After normalization, open and close slide/tilt sunroof fully once by pressing switch.

In the event of faulty triggering of the anti-trap protection facility in specific positions, the fault can be rectified by moving over the relevant position numerous times.
